A machine concept designed to meet the highest standards in grinding the tooth sides of carbide-tipped circular saw blades. With the CHF 270, you get a machining tool with outstanding qualities: As a standalone machine or with automatic loading for saw blade production. The seven CNC axes are compactly and robustly mounted on a central main structure (monoblock design). This ensures maximum stability, quiet running and precision for all tooth geometries.
Each saw blade is positioned automatically as it moves into the grinding position regardless of its diameter. A measuring sensor then determines the tooth geometry, such as the hook angle, radial and tangential clearance angles, cutting width, blade thickness and side projection. A high degree of precision is essential for ensuring accurate grinding results at a later stage.
VOLLMER's control technology makes it exceptionally easy to operate this machine. The grinding programs, including those for convex tooth sides, are already integrated as standard and can be set and accessed using the menus on the control panel. The clear text on the LCD color display, supported by graphics, guides the operator through the program and also provides them with important information to help them rapidly eliminate any faults which may occur. It is possible to program a saw blade while another one is still being machined.
